Heavy alkali metal-arsenic alloys intercalate easily into graphite, leading to the formation of a new family of ternary graphite intercalation compounds (GICs). Pure phases formulated as MAsxC4s (M = K, Rb or Cs; s = stage; x ≤ 1) have been synthesized at the laboratory. This article aims to expose all physical measurements performed on these inter...
Intercalation reaction occurs when an excess of a liquid heavy alkali metal-arsenic alloy is contacted with a graphite sample under vacuum. This leads to the formation of several novel ternary phases. X-ray structural analysis was conducted to determine how intercalated metallic alloy is arranged between the graphitic layers. The results have shown...
